Description
Technical field
The utility model relates to the auxiliary switching-off device of a kind of circuit breaker.
Background technology
Circuit breaker is can close to close, carry and cut-off the electric current under the normal loop condition, and can close the switching device that closes, in official hour, carries and cut-off the electric current under the unusual loop condition (comprising short circuit condition).Circuit breaker is divided into primary cut-out and low-voltage circuit breaker by its scope of application, generally rated voltage is called primary cut-out more than 3kV.Primary cut-out (or claim high-voltage switch gear) is the main electric control appliance of power plant, electric substation, because of its voltage of controlling higher, in order to realize reliable turn-off, must have arc quenching characteristic.When system normally moved, it can cut off and connect the zero load and the load current of circuit and various electric equipments; When system broke down, it cooperated with relaying protection, and ability is the disengagement failure electric current rapidly, to prevent expansion accident scope.Therefore, the quality of primary cut-out work directly has influence on the safe operation of electric power system.The primary cut-out kind is a lot, and the difference by its arc extinguishing can be divided into: oil circuit breaker (bulk-oil circuit-breaker, oil-minimum breaker), sulfur hexafluoride breaker (SF6 circuit breaker), vacuum circuit-breaker, compressed-air circuit breaker etc.Wherein, Vacuum circuit-breaker by feat of its be suitable for reclosing operation and high operating reliability is arranged and useful life (can in current margin, carry out frequent operation or repeatedly open, disconnected short circuit current; The tool life-span can be up to 30; 000 time, full capacity short circuit current open and close times can be up to 100 times), and in the general transformer station that is applied to newly-built, reorganization and expansion.
In order to improve the reliability that opens circuit, vacuum circuit-breaker has generally all installed urgent manual brake separating mechanism additional, mainly comprises an interlocking handle that is installed on the housing and the pressure button that is used with the interlocking handle.When running into switch cubicle electric loop fault,, can force separating brake to open circuit through urgent manual brake separating mechanism if vacuum circuit-breaker can not open circuit by regulation.Specific operation process is: rotate the interlocking handle with a hand, will force the button release, push the pressure button with the another hand then, vacuum circuit-breaker promptly is forced and opens circuit like this, has guaranteed the reliability that opens circuit.There is more uncertain factor in operating charging equipment, and nobody can guarantee that the fail safe of urgent manual switching-off device is a hundred per cent.If this moment, the switch opening velocity was slow slightly, must produce electric arc, the people is got an electric shock, cause danger, though therefore force sub-switching operation thoroughly to open circuit, dangerous higher.
The utility model content
The technical problem that the utility model will solve is to provide a kind of rational in infrastructure, safe to above-mentioned deficiency, and the auxiliary switching-off device of easy to operate circuit breaker.
For solving the problems of the technologies described above; The design feature of the auxiliary switching-off device of this circuit breaker is: comprise the operation panel that can be installed on the case for circuit breaker; Operation panel is provided with and can promotes the electromagnet that circuit breaker is forced button actions; Be electrically connected with the switch of control work of electromagnet in the supply access of electromagnet, also be provided with on the operation panel and the corresponding operation window of circuit breaker interlocking handle position, operation panel is provided with spacing position-limit mechanism is carried out in interlocking handle released state position.
The auxiliary switching-off device of the circuit breaker of this structure is to come implementation structure reasonable through fixed limit and remote electrically controlled structure, and is safe, and easy to operate.
Fixed limit mainly comprises the operation window that is arranged on the operation panel, and operation window is corresponding with the interlocking handle position of circuit breaker.When being fixed to operation panel on the case for circuit breaker, the interlocking handle just is presented in the operation window.Operation panel is provided with position-limit mechanism, and the main effect of position-limit mechanism is that the position during to interlocking handle released state is carried out spacing.When needs carry out release to forcing button; Firmly interlocking handle dominated by hand also turns to unlocked position, and is with position-limit mechanism that the interlocking handle is spacing then, so just need not to control the interlocking handle with hand more always; Can realize the isolation of human body and circuit breaker, the fail safe when having guaranteed to force separating brake.
Remote electrically controlled structure mainly comprises the electromagnet that is arranged on the operation panel; Electromagnet position and the corresponding setting of pressure button positions; Like this through being arranged on the switch on the electromagnet power supply line; Action that just can the far distance controlled electromagnet, thus the iron core of realizing electromagnet promotes the action of forcing button to be pressed, has guaranteed processing safety.
As a kind of implementation; Said position-limit mechanism comprises the sliding chamber that is arranged in the operation panel; Being fitted with in the sliding chamber can be to the cylindrical slide bar of interlocking handle slip through operation window, and the operation panel outer wall is provided with the slideway corresponding with the slide bar motion track, and slideway is communicated with sliding chamber; Be installed with the handle that is slidingly matched with slideway on the slide bar, slideway is provided with when slide bar is spacing to the interlocking handle and the screens groove of handle clamping matching.
This position-limit mechanism is to realize spacing to the interlocking handle through the card bit architecture.Because the glide direction of slide bar and interlocking handle released state towards being consistent in the sliding chamber; Therefore; When forcing separating brake, the interlocking handle is turned to unlocked position, in sliding chamber, release slide bar through handle then towards the interlocking handle; And make the slide bar outer end withstand on the interlocking handle end, rotate slide bar and make the handle screens in the screens groove through handle at last.After operating personnel loosed one's grip from the interlocking handle, the interlocking handle just kept released state because of the screens supporting role of slide bar, like this, had just realized the fixing of interlocking handle unlocked position, need not the nearly body operation of operating personnel, and operation is very easy.
As improvement, operation panel is provided with slide cartridge in two ends up and down, is fitted with the extension rod that slides along slide cartridge in the slide cartridge, and the extension rod outer end is installed with the hook that is hooked on case for circuit breaker, is bolted with the locking nut that extension rod is locked at slide cartridge on the slide cartridge.
Through the sliding position of adjustment extension rod in slide cartridge, can regulate the hook position of extension rod end hook, like this, no matter be what size circuit breaker, can the hook hook be got on, and be locked with locking nut, it is very convenient to operate.
In sum, adopt the auxiliary switching-off device of circuit breaker of this structure, rational in infrastructure, safe, and easy to operate, be adapted at doing on the various circuit breakers aid of forcing separating brake and use.
